Activist investors Carl Icahn and Barry Rosenstein acquire a stake in Oklahoma-based company Kerr-McGee. They demand two board seats and ask the company to make several operational and financial changes, including the repurchase of equity and divestiture of their chemicals business. The case protagonist, Luke Corbett, CEO, opposes these changes.

In June 2015 William A. Ackman, the CEO and founder of New York hedge fund Pershing Square Capital, reflects on the success of the fund he has spent over a decade building. Since its inception in 2004, Pershing Square's assets under management had grown from $500 million to well over $18 billion. Ackman is now considering a sizable new portfolio position and must decide how he should raise capital to undertake this new investment. This choice is affected by the recent launch of his new, $6 billion closed-end vehicle, Pershing Square Holdings, as well as the firm's lengthening investment horizon. Although always activist in nature, Ackman and his fund had in recent years become substantively involved in the management of portfolio companies, often working to drive shareholder value by improving operating performance.
